3. Functional design
4. Code Example
In order to simplify the code example, we only implement the form creation and saving functions. First, create a PHP file index.php that will display the form builder page.
<!DOCTYPE html> <html> <head> <title>在线表单生成器</title> <style> /* CSS样式 */ </style> </head> <body> <h1>在线表单生成器</h1> <form action="save_form.php" method="POST"> <label for="title">表单标题:</label> <input type="text" name="title" id="title" required><br><br> <label for="fields">字段:</label> <textarea name="fields" id="fields" required></textarea><br><br> <input type="submit" value="保存表单"> </form> </body> </html>
Next, create a PHP file named save_form.php to save the form.
<?php // 连接数据库 $servername = "localhost"; $username = "root"; $password = ""; $dbname = "forms"; $conn = new mysqli($servername, $username, $password, $dbname); // 检查连接是否成功 if ($conn->connect_error) { die("连接数据库失败: " . $conn->connect_error); } // 获取表单数据 $title = $_POST['title']; $fields = $_POST['fields']; // 保存表单到数据库 $sql = "INSERT INTO forms (title, fields) VALUES ('$title', '$fields')"; if ($conn->query($sql) === TRUE) { echo "表单保存成功!"; } else { echo "保存表单时发生错误: " . $conn->error; } // 关闭数据库连接 $conn->close(); ?>
Finally, create a MySQL database and create a table named forms to store form information.
CREATE DATABASE forms; USE forms; CREATE TABLE forms ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, title VARCHAR(30) NOT NULL, fields TEXT NOT NULL );
